The Spiral Model: A Viable Software Development Methodology for Large Projects
For every custom software solution project, whether large or small, a suitable software development methodology is the core requirement in the development procedure. Every company employs a particular model to ensure the software development process is implemented with ease and professionalism. One such methodology is the spiral model.
The spiral model combines the design and prototyping-in-stage factors for a perfect software development process to take place. It is also known as a spiral lifecycle model that boasts the advantages of top-down and bottom-up concepts. This SDM (systems development method) used in the IT field is generally intended for large, complicated and expensive software development projects.
The spiral model was the first model to explain the importance of iterative or step-by-step development. The iterations were envisaged to be 6 months-2 years long. The phases began with design goals and ended with the client reviewing the progress.
The step by step process can be defined in brief as follows:
- Defining new system requirements
- Creating a preliminary design for the new system
- Creating an initial prototype for the new system
- Creating a second prototype has to follow a four-fold procedure:
- Evaluating the first prototype in terms of its strengths and weaknesses
- Defining the second prototype’s requirements and
- Planning, designing, creating & testing the second prototype.
- Prototyping at each stage in the systems development ensures quality assurance.
Most large software development projects needs constant reviews to achieve the required target. Moreover, there are many development hurdles. In such cases, a software solution company works closely to analyze the hurdles and challenges.
A typical software solution UK generally follows the Spiral model as a viable management lifecycle model. It creates perfect solutions that are geared towards business values leading to optimal advantages to clients. In the software solutions UK scenario, consultants develop solutions by evaluating the actual client requirements and developing perfect software methodologies for accurate products to be delivered to the client.
